Procedure for pressure generator models CH1-1250B
> Hydraulique diagram
The model CH1-1250B have 2 valves
A
and
A’
for multiple round and return of the piston to fill
the devices to be tested. The valve
A’
shall be used only for filling, it must remain open.
>
Pressure mounted
> Observe the maximum operating pressures
of the pressure generator
Maximum operating pressure : CH1-1250B
1270 bar
a)
Connect the instrument to be tested (G1/2<1200bar / M16x150>1200 bar)
b)
Check the valves
A
,
A’
are open (the valve
A’
is not marked on the crankcase).
c)
Check the capstan
1
pressure generator is in the end position.
d)
Close the valve
A
e)
Turn the capstan
1
in the direction of clockwise
f)
If the resulting pressure is not sufficient
g)
Close the valve
A’
h)
Open the valve
A
i)
Turn the capstan
1
in the opposite direction of clockwise.
j)
Close the valve
A
k)
Equalize the pressures by turning the capstan
1
in the direction of clockwise.
l)
Open slowly valve
A’
m)
Repeat steps e) to j) again if necessary to achieve the desired pressure.
n)
Realize the measurement point.
